Three of them are unstable, but the other two can be stable given a sufficiently high mass ratio. These components of the circular restricted three-body problem solution contain the Trojans Asteroids and at these locations the net gravitational pull is precisely equal to the centripetal force necessary to maintain a common orbit. For 10 points, name these positions where an object will remain motionless with respect to the orbit of two larger bodies, named for a French-Italian creator of the calculus of variations and a namesake multiplier.
